Abstract

A portable electronic instrument that has a connection port for inserting a connector and includes a built-in spring having a protrusion portion protruding in a lateral direction inside the connection port, a connector 10 has an insertion portion 12 which is inserted in the connection port 16 and includes connection members 31, 32 which respectively have hooking portions 23, 24 able to be hooked at the protrusion portions of the built-in springs inside a main body.

1 . A connection device of a connector for a portable electronic instrument that has a connection port for inserting the connector and includes a built-in spring having a protrusion portion which protrudes in a lateral direction inside the connection port,
 wherein the connector has an insertion portion which is inserted in the connection port of the portable electronic instrument, and includes a connection member which has a hooking portion able to be hooked at the protrusion portion of the built-in spring inside a main body, and   wherein the connector is configured to include an operation member which is provided in the main body so as to be slidable in an insertion direction of the insertion portion in order to move the connection member in the lateral direction, an engagement member which is integrally provided with the operation member in order to convert a slide operation of the operation member into a movement of the connection member in the lateral direction, and a cam portion which is provided in the connection member so as to engage with the engagement member.   
     
     
         2 . The connection device of a connector for a portable electronic instrument according to  claim 1 ,
 wherein the connection member is formed with a pair of right and left opening/closing levers, and each of the opening/closing levers is configured to have the hooking portion at a tip end portion, to have the cam portion on a side of a base end portion, to have a fulcrum between the tip end portion and the base end portion, and to be able to pivot around the fulcrum.   
     
     
         3 . The connection device of a connector for a portable electronic instrument according to  claim 1 ,
 wherein the pair of right and left opening/closing levers has a bilaterally symmetrical shape including the hooking portions respectively provided at the tip end portions so as to be oriented toward the right and left sides and including the cam portions respectively provided on the right and left side surfaces of the base end portions, and each of the cam portion is configured to be on the base end portion side beyond the fulcrum provided between the tip end portion and the base end portion and to have a form in which the width is the lateral direction is widened in a direction toward the fulcrum.
